I was working on same idea but left in between and thank god they did it.

Why I left that idea is because as a developer I know that was needed but I have limited time so I need to build that is really next path forward.

I am working on whole dev space that can run on my Mac M4 or similar specs. I needed to revamp everything (LLM thinking) from ground up even models. My idea is mixing deterministic nature of existing tooling (non-LLM tooling) with non-deterministic nature of LLMs.

Tell me more about the ideas behind Cordis the plugin system. The paper is a bit too mathy to consume and I think it deserves a more accessible post or something.

You're making demands (like you would to an llm) instead of asking questions (like you would to a human). The GP didn't even offer to answer questions

He explicitly asked for feedback

Yeah. LLMs have their place and they are definitely super human at short length tasks, but I feel like a large part of the "AI boom" is trying to get the computer to do something in a worse way then it already could.

But that "worse way" makes AI labs and investors a lot of money... If the perception that "worse" is accompanied with needing less human intervention, i.e. less labor, worse is better from a business perspective...

How does a git hook need more labor than an LLM?

Hi I'm one of the authors of DeepSeek Harness. It's just an early developer preview version we're presenting in MIT license currently. Expect lots of rough edges and compatibility-breaking changes. Any feedback and suggestions are more than welcome!

congrats! the paper that is published alongside this (Cordis) is super interesting. has anyone on the team given a talk or published a talk about this? would love to hear the authors break this down

New coding harness that seems to have some novel concepts and one of the pretty cool things on their landing page for it here: https://deepseek.com/harness/en/ is the Every Run is Traceable view: "Everything the model sees is recorded in an append-only session log: system prompts, reasoning, tool calls and results, subagent scheduling, and every context injection. In the Trajectory view, you can inspect these records…

I promise this isn't meant to be snarky, but is that not just...logs?

Which are unavailable with the leading American models. You can't look at the complete traces of OpenAI or Anthropic model agents, as they are encrypted (there's been discussion of a couple of different ways to expose those, but that violates terms of service, and well, you shouldn't have to find complicated ways unencrypt your own usage logs).

Tangential but, are there benchmarks out there on how languages affect latent spaces and performance of these models? This other day I was looking at that “caveman” skill, and was shocked to see it evolved to become a company, and, in one of its modes, the highest form of compression seems to be “Wenyan” which is Classical Chinese. Should I get started on learning Chinese?

It's interesting to note that the newer LLMs like deepseek v4 or kimi k3 basically use caveman mode natively for their thinking traces. Lot word dropping when thinking.

1. it's built for async 2. runs everywhere 3. interpreted, making it fast to iterate on 4. decent performance 5. most popular language, llms are decent at writing it

JVM has real and virtual threads and arguably just as good if not better on all these points. (I actually have/am writing a harness in Java fwiw, but mostly as a hobby/experimentation)

I hate nodejs and the npm ecosystem more than most, but Java, really?

I just started testing, but didn't figured out if it already support MCP/plugins? It seems it can already use Deepseek search if it uses official API, but what about custom providers? Can we use together with MCPs like tavily?

Also isn't OpenAI's Codex written in Rust?

I don’t think so it’s an npm package iirc

Reasonix (which has been seemingly the most recommended harness for using DeepSeek, as it is designed around maximizing caching in DeepSeek) is now a Go app, but still installed via npm. Which feels ugly, but I guess everyone has npm already, and it handles binaries, so I guess it's a reasonable choice.
